I can’t speak to its effectiveness on regrowth yet. However, it made my hair feel really soft and after washing it didn’t weigh it down. Also made it very shinny and helped with the winter static! My scalp also felt good! I will continue to use this. The smell is heavy coffee, but not bad! I use the artnaturals brand a lot. I have fine hair and a medium amount.

Smells strong

Package was delivered YESTERDAY. Haven't had time to evaluate the product. Only comment is the smell is pretty strong but dissipates within 15 minutes.
